Efficiency of polymer materials in highly loaded systems in the aviation industry
Aviation, 2023 The static coefficient of friction was calculated on an inclined plane tribological stand. Different specimens and masses loading the system were used during the experiment. Surface-to-surface contact was tested in a pin-on-plate setup.

A Brake System Coefficient of Friction Estimation Using 3D Friction Maps
Lubricants, 2022 The coefficient of friction (COF) is one of the core factors in the evaluation of brake system performance. It is challenging to predict the COF, since it is strongly influenced by several parameters such as contact pressure (p), slip rate (v) and ...

FRICTION COEFFICIENT DISPALYED BY SLIDING SURFACES LUBRICATED BY SAND CONTAMINATED OIL [PDF]
Journal of the Egyptian Society of Tribology, 2014 The present work discusses the effect of sand particles, contaminated in the lubricating oil, as well as sand particles embedded in the sliding surfaces, on the friction coefficient displayed by polyamides sliding against steel. Stribeck curve is used to

Phenomenological contact line friction coefficient
DropletAn important feature of contact line motion, as an irreversible process, is its dissipative nature, which can dominate the dynamics during the early stages of droplet spreading.

FEBS Open Bio, EarlyView.The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

FEBS Open Bio, EarlyView.Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Discordance Between Patient and Physician Global Assessments in Early Systemic Sclerosis
Arthritis Care &Research, EarlyView.Objective This study aims to identify factors associated with patient global assessment (PtGA) and physician global assessment (PhGA) and discordance between them in systemic sclerosis (SSc). Methods Data from adults with early SSc (<5 years) from the Collaborative National Quality and Efficacy Registry were included.
